To @ZZ whom t may concern.'`

Be it known that I, GLENN A.. HART, a citizen of the United States, and a. resident of Bell, county of Los Angeles, State of California, have invented a certain new and useful Walking-Beam and Sucher-Rod Connection for Deep-l/Vell Pumps; and l hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like numerals refer to lil/:e parts.

This invention relates toy a` connection between the walkingbeam andsucker rod of a deep well pump, and an-object of this invention is to form a flexible connection between these parts that is simple to construct, op-erate and' install; and that is -very strong and-durable in use. j

Another object of the invention is to provide a flexible connection between a walking beam and sucker rod o1 a deep well pump that includes short cables that are arranged and connected so that they are held straight;

so that substantialy all the weight and .strain appliedto them is lengthwiseV thereto.

Heretofore it has been customary to loop a cable either under orl over appliances secured to a rwalking beam with the end of the cable connected to a cross bar on the sucker rod so that they weight and strain were crosswise to the cabl-e adjacent its center; which arrangement ot parts required long length of cable; and also the crosswise strain and weights caused the cablev to be easily and quickly broken at the loop; and as stated an object is to av id crosswise `strains on the `cables and also to use short lengths of cable.

Another object of the invention is to provide a flexible connection between the walk` ing beam and sucker rod 0rp a deep well pump that includes cables having end bearings that are adapted to be pivotally connected to pivots carried bythe walking beam and another pivot on a cross barconne'cted to the sucker rod so that the bearings can move on their pivots to compensate for the dinerence between the are movement of the walk` ing beam and verticalmovement of the rod.

Another object of the invention is to provide a simple, strong and durable rocking saddleI for the' walking beam that is adapted to reciprocate in its' seat= to aid holding' the cables' straight, so that the weight or lm@veine-nt of the cross The deep well pump l has aE sucker' orY strain will not be applied crosswise thereto.

Another object is to provide the cables of the connection with detachable end bearings, that, in addition to reciprocating on their pivots s0 that the cables will remain straight in operation, also are interchangeable to expedite connecting' or disconnecting` the cables to the beam and rod.

Features of invention are Vshown in the construction, combination and arrangement oi the parts whereby a flexible connection is provided that in operation is adapted to im# part a .slight intermittent rotary movement to the sucker rod to keep its joints' tightly screwed together. i p

Other objects, advantages and features of invention may appear from the .accompanying drawings, the subjoined detailed description and the appended claims.

. rhe beam. 3 is ot usual construction and is mounted on a pivot not shown and operated in a wa)v rell unde1 ,ftood in the art, it being understood that its purpose is to reciprocate the rod 2 vertically. find it is also understood that the flexible connection between the walking;` lizeam and sucker rod is for the purpose ot slightly rotating` the suele er rod to keep its joints et screwed tiejhtljy together as well to operate the 'odg rad to accomplish the toregoing purposes 1 provide a connection comprising two units c and d that coact to reciprocate and simultaneously rotate. the rod; and the parts ol' these units are constructed stantiall).v alike except that the calles ot the unit' c are slins'htljv shrrter than the cables G o1 the unit (Z.

T he walking beam is provided with groove seats i', S in which the rock saddles tl, 10 are looseljv mounted.

llreterahlj' the saddles tl. 10 are formed ol" cylilulrieal iron bars that are lirst lient to itorm si( e portions 1l that are arranged to extend down the sides o t the beam; and then end portions 1'2 are bent outward to itorm pirots `lor lvaring's lpot the bearing plates 14.

yl`he hearingplates 141; are onslrueted substantially alike so that the.;v can be titted to an)v ot the pivots 1Q ot 'the saddles 7, S or also to any ot the pivots l5 of the upper and lower cross bars 1G.v 1i' that are adapted to he looselj,7 mounted on the sucker rod and arranged to engage their respective clamps 18t 19 that are seoured to the rod In other words the hearing plates are interchangeable to expedite attaching them to or detaching them 'from the pivots on the saddles and cross be Each ot the bearing` plates 1l is jnovided with parallel groovesvtl in one side theremC that extends eroffswise to the longitudinal axis ot' the plates; and Yfrom the. bottoms of these `:Irotwes there are `:airs ot holt holes 21 that extend through to the other side ot the plates.

The grooves Q0 are arranged so that end portions ot the pairs ogt cables 6 can he laid across them lengthwise to the plates and secured thereto hj' Ll-holts that are, air-- rangedy over the cables G that when the nuts Q3 are tightened the cables will he drawn a sutlieieut distance into the cross grooves to secure the cable ends and hearing' plates together so that the)- will sustain great strains and weight without separatinY or hrealing.

The various parts ot the connection between the walking` beam and sucker rod are Constructed and arranged so that the cables 5, G are held straight, so that the strain and weight thereon wnen reciprocating the sucker rod will be in lines parallel to the longitudinal axis ot the cables and never crosswise thereto. In other wo 'ds the saddles are constructed and arranged so that they can rock in the seats 7,

o and the hearing plates 11 can turn on their pivots to compensate 'tor the ditiierence between the are movement ol the vz'alkingj' beam and vertical movement of the sucker rod as previously stated.

The unit e, is shorter than the unit d and arranged rith its saddle D ner-.rer to the pivot (not shown) ot the walkingA beam Q so that it moves in a much shorter arf.l than the unit d; and the clamps 1S, 19 are arranged on and secured to the rod 2 so thatI when the beam il is moved in the are (15s-7) the strain and weight ot the, .sucker rod will he alternately shitted Vfrom unit ff lo f1 and vice versa.

As previously stated, the cables be slightljY twisted so that when r-feight or strain thejv norniallj; hold 5.1i atan acute angle relatire lo a hue parallel to the longitudinal axis ot' the sarl dlr-sasilluslraledln'the dotefl lines# Y faitl m--A/ in Fig'.
